Description of problem:

ipv6_addr_type() doesn't check for 'Unique Local IPv6 Unicast
Addresses' (RFC4193) and returns IPV6_ADDR_RESERVED for that range.

SCTP uses this function and will fail bind() and connect() calls that
use RFC4193 addresses, SCTP will also ignore inbound connections from
RFC4193 addresses if listening on IPV6_ADDR_ANY.
